Do you mean the hip itself or the very lower back (upper arse) above the hip? If the latter yes, I've suffered that on a bike (it's what caused me to sell my then 6-month-old '06 1200GS) - it was sciatica associated with a slipped disk I'd suffered a couple of years earlier. Anything more than 20 minutes on the bike became increasingly painful - not good on a 1 hour commute.
Possibly non-medical remedies are changing the bar position to tip your upper body forward/back (changes the part of your backside that takes your upper body weight), changing the bars for alternative ones (higher/lower/different pull-back etc), fitting bar risers/bar-backs, trying a different seat, different seat height or different seat angle (high at the front, low at the rear).
If you've ridden similar bikes before with standard seats and not had a problem I'd suggest trying a standard seat on your bike - that may well solve the problem. Not all seats suit all people. Loads complain about the standard one but I have no problem with it.
